BEAVER DAM (AP/WLUK) -- A team of explosive experts detonated highly-volatile chemicals at a Beaver Dam apartment where a man was killed in an explosion earlier this week.

Officials haven't identified who the man was.

Police Chief John Kreuziger said in a news conference Wednesday the chemicals could not be removed from the apartment because of their volatility, so the specialists conducted a controlled detonation later in the day. The detonation caused additional damage to the apartment building. Some tenants at the complex have been displaced since Monday's explosion.

Officials believe Monday's explosion may have been an accident, but are still looking into it.

Even though the chemicals couldn't be removed from the apartment, authorities were able to remove the man's body as well as "pertinent evidence" involved in the case.

Police say there were no other hazardous materials in the area. They are unsure of how the chemicals were acquired, and are still investigating.

Kreuziger says the investigation involving federal, state and local authorities continues into why the man possessed a significant amount of explosives.
